First you bleed… … then the terror begins.

From afar, the old Romero House looks like a decrepit old mansion, reputedly haunted. But what the locals don't know is that behind the facade of the ancient building, the US Government has built one of the world's most gruesome experiments - a horrifying, genetically engineered, menacing carnivorous beast.

When the project's chief, Dr. Westmont, underestimates the strength and intelligence of the monster, he meets a bloody fate and suddenly, the creature is free to roam the house. At the same time, four local teens sneak into the house to spend the night and what began as a night of fun turns into a chamber of horrors as they race to save themselves from the Carnivore.
